Green Ideas Soil Lamp: Making Light From Mud

What happens when you combine plants with lighting? Something Green! The Soil Lamp is an innovative concept that was designed to nurture the biological organisms that it contains. It's similar to powering electronics from lamps, but it accomplishes something different. On top of that, this lamp runs on mud! Now, that's a really green idea.

The Soil Lamp was designed by Marieke Staps. It's made out of mud and glass. A stark looking LED light powers the whole apparatus. It's even more incredible that this lamp actually runs on... mud. Yep, that's not a typo, it runs on mud! Now how's that for eco-friendly? We can think of many applications of something like this. How about street lights that run off the electricity generated directly in the earth?

The metabolism of the biological organisms produces enough electricity to keep the light burning. The mud is contained in cells, which in their turn contain copper and zinc that conduct the electricity. The more cells there are, the more electricity is produced. The only thing that the light needs from time to time is a splash of water to keep it going. That's pretty amazing. [via Make]
